Riley had Cody Hoffman and I think one year of Jamaal.
Taysom had Jamaal plus several strong receivers including Mitch Mathews
Tanner did have the benefit of good receivers in ‘15, and played well with them. He also pulled a hammy mid ‘15 (playing straight off a mission with minimal prep) that impacted him the rest of that season, and put a bit of a damper on things that yr.
So context is important in interpreting W-L stats.
